About
Sean Walsh

Having worked in the private sector, state government and in academia, Sean Walsh is a passionate environmental scientist specialising in large and complex simulation systems. Sean’s PhD is using conceptual and mathematical models to examine the response of fire-adapted ecosystems to increased pressure from altered fire regimes and climate, with particular attention to the role of seed ecology. Temporal, spatial and floristic dynamics will be examined through systematic development of tractable models, sensitivity analysis and comparison with available observations. The separate and combined effects of management intervention and climate change will be assessed using plausible future scenarios. A key theme in Sean’s study is to investigate factors which limit the ability of canopy and soil seed banks to buffer populations against changes in composition.
